Preheat your oven to 350°F (175°C).

In a large mixing bowl, combine the cake mix, eggs, and vegetable oil.

Add the vanilla extract and optional ingredients like sprinkles or chocolate chips.

Scoop tablespoon-sized portions of dough onto a baking sheet lined with parchment paper, spacing them a couple of inches apart.

Bake for 8-10 minutes, or until the edges are lightly golden.

Allow the cookies to cool on the baking sheet for a few minutes before transferring them to wire racks to cool completely.
